(2) The hydrocyanic-acid content of the dried and powdered plant was still very high, namely 0·26 per cent. and the view is expressed that the cyanogenetic glucoside may be constituted by the combination of a sugar, benzaldehyde and hydrocyanic-acid. Further results will follow when more of the fresh plant has been obtained.en© ARC – Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © University of Pretoria.
